SMTA gears ... 52/21 = 2.48
SMTA with TA low ... 2.48/.7 = 3.54
M gears ... 44/19 = 2.32
Low/low M gears 49/? = ?
560 gears ... 54/19 = 2.84
560 with TA low ... 2.84/.70 = 4.05

Here ya go. I included the 560 gears because they will fit the SMTA tranny and are an option for someone who wants to slow down tractor in first gear.

The net effect is that a SMTA with 560 gears will run at 57% of the speed of a M at the same engine RPM. If you put the 560 ring gear and tranny main shaft, it will be about 55%.
